// define globally function stuffify(match, group1, group2) {   switch (group1 || group2) {     case 'http':       return '<a class="twtr-link" target="_blank" href="' + match + '">' + match + '</a>';     case '#':       return '<a class="twtr-hashtag" target="_blank" href="http://twitter.com/search?q=' + encodeuricomponent(match) + '">#' + match + '</a>'      case '@':       return '<a class="twtr-atreply" target="_blank" href="http://twitter.com/intent/user?screen_name=' +  encodeuricomponent(match) + '">@' + match + '</a>';     default:        return match;   } }  function(data){   tweetsloaded = true;   var interestingparts = /(http):\/\/\s+|(#|@)[^\s.,!?;^()\[\]<>{}]+/g;    $.each(data.results, function(i,item) {     var newtext = item.text.replace(interestingparts, stuffify);      $("#twitter_results").append('<li class="twitter"><img class="twitter_img" src="' + item.profile_image_url + '"/>'+ newtext + '</li>');   }); }
